Guest Enzo Posted September 1, 2009 Share Posted September 1, 2009 hi thought id start a write up on turbo options, il keep working at it but if any of you can add to it feel free.hi flow turbo - expandhybrid turbo - expandexternaly gated setups - expanddifferent trims and compressor maps -expanddifferent turbo rangestd seriesMitsubishi Heavy Industries' (MHI) turbocharger nomenclature, such as TD04-13G-6cm2, requires some explanation. "TD04" and "TD05" refer to the turbocharger housing (either turbine housing or compressor housing or both), including the center housing (or CHRA or cartridge section). There are different styles of the basic housings and these have different suffixes appended to the basic designation, such as TD04L, TD04H, TD04HL, TD05, TD05H, and TD05HR.Mitsubishi does not seem to use seperate designations for different size turbine wheels, other than the TD04, TD04H, TE04, TD05H, etc., designation. The "6cm2" in the model name is similar to the A/R ratio used by other manufacturers.Like A/R, the smaller the size of the "cm2" number, the faster the exhaust gases will discharge onto the turbine wheel, and so the faster the spool up will be (less "lag"). The size of the "cm2" number or the A/R ratio also determines the amount of exhaust gas backpressure and, thus, reversion into the combustion chamber. A larger "cm2" number (or larger A/R) means less backpressure at high exhaust flow.6 cm2 = 0.41 A/R7 cm2 = 0.49 A/R8 cm2 = 0.57 A/R9 cm2 = 0.65 A/R10 cm2 = 0.73 A/R11 cm2 = 0.81 A/R12 cm2 = 0.89 A/R-tdo4 141 different varientsvf seriesgarret seriesgt spec (180-200)td12 (200-240)greddy tdo4 11b (190-210)mitsubishi tf035 (200-250) found on forrester turbos. a smaller more responsive turbo to the tdo4tdo4L 13G (200-240 *270 forged 1.6bar) very popular turbo upgradetdo4h 15G (200 - 240 *280 forged 1.6bar) found on the mitsubishi evo. has a different bolt flange. note the H stands for high capacitygreddy tdo5 12g smallest of the tdo5 range almost aking to a tdo4. is capable of more power and responds like a tdo4 in most cases.tdo5h 14btdo5 16g.

RobSR Posted September 24, 2009 Share Posted September 24, 2009 I've got some pics of a greddy 18g if your needing some. Aswell as HRF tub kit pics.. Also Is there anyway I can upload an excel file to the forum? If not I'll whack it on me server and link it here.. Quote Link to post Share on other sites
